Vevey calls itself 'Ville d'Images', which I've always thought is a slightly pretentious title (Ville sold out to Nestlé would be far more accurate...), but the recent 'Festival d'Images' had some good bits: including this fake horizontal house, reflected in a mirror. Kids and adults had a whale of a time playing on it, and I was impressed by the children's ability to think up 'suspenseful' situations and translate them into horizontal positions.
